[PATCH v2 2/4] arm64: dts: imx8mp-kontron: Drop vmmc-supply to fix SD card on SMARC eval carrier

From: Frieder Schrempf

Date: Fri Feb 20 2026 - 05:39:10 EST


From: Frieder Schrempf <frieder.schrempf@xxxxxxxxxx>

The SMARC evaluation carrier provides an SD card power switch that
complies with the OSM standard definition. The OSM base devicetree
already describes this correctly.

Stop overriding the vmmc-supply in the board devicetree and rely on
the definition from the OSM base DTS instead to fix the power supply
configuration for the SD card.

Fixes: 6fe1ced5ccab7 ("arm64: dts: Add support for Kontron i.MX8MP SMARC module and eval carrier")
